CAR-BOLSTER.

To f/,ZZ whom, it Imay concern.'

Be it known that I, ETHAN I. DoDDs, a citizen ofthe United States,residing at Pullman, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Car-Bolsters, of whichthe following is a specification.

My invention pertains to car-holsters; and its principal objects are theproduction of such a structure which shall provide great strength, whichshall be comparatively economical in the cost of manufacture, and thedepth of whose sides may be varied to some extent. The bolster has itsbellied sides integral with the bottom plate at its central portion, andat the intermediate inclined and horizontal endportion of the sides thebottom is riveted to inturned flanges integral with the sides. At theupper portion of the sides Irivet angle-bars with outwardly-extendedflanges, to which may be secured a top plate. In addition, if desired, Imay connect the upper parts of the side plates by achannel-bar rivetedthereto.

In the accompanying drawings I have illustrated two embodiments of myinvention, whcrein- Figure 1 is a longitudinal vertical central sectionof a body and truck bolster both embodying my invention. Fig. 2 is anenlarged end view of' the two bolsters as shown inFig. 1. Fig. 3 is anenlarged cross-section on the i lint,` 3 3 of Fig. 1 as viewed in thedirection indicated lby the arrows.. Fig. 4.- illustrates the blank`from which the body-bolster is constructed. Fig. 5 illustrates asimilar blank from which the truck-bolster is constructed, and Fig. (jis a perspective view of a modified l'orm of truck-bolster.

Inaslnuch as both bolsters are made from blanks which are similar in allrespects, a description of the body-bolster blank shown in Fig. 4 willsuIIice for both constructions.

'lhc body-bolster is made from a rectangular sheet of metal by cuttinginwardly from each end two parallel cuts on the lines 11 l2. 'l`he sheetis then shcarcd on the lines 13 14 and 14 l5, four of each of these cutsbeing made, :is shown in Fig. 4, the point 15 where the line 14 15 meetsthe line 11 1-2 being some distance from the point 12. By means oftht-,sc cuts two tapering iecespf metal are removed from each end,eaving the four recesses shown on the drawings.

` as the body-bolster.

Patented .Tiny 3, 1906.

In order to provide integral flanges for portions of the lower edges ofthe parts which areto com rise the side plates of the bolster, I bend upt ie flanges 16 on .the bent lines 17, the same extending from points 12to the ends of the bolster. The outer longitudinal portions 18 of thesheet'lO, which are to form the sides of the bolster, are then foldedyupon the lines 19 19, joining the points 12 12,' so that the sides willbe at right angles to the central bottom portion 20. The central stripof the sheet which forms the bottom of the bolster is then bent on thetransverse lines 21, so that the portions 22 will be inclined and lieagainst the inclined ortions of flanges 16. The central strip is a sobent on the lines 23 to provide the end horizontal portions 24 of thebottom, so as to lie against the horizontal portions of the flanges 16.When the bolster is thus formed to shape, the bottom is riveted to theintegral side flanges 16, as shown in Fi s. 1, 2, and 3.

It will be evident from this escription how the main portion of thetruck-bolster is made, since it is constructed identically asset forthabove and differs from the body-bolster only in respect to size.

Adjacent to the upper edge of each side of the body-bolster I rivet theangle-bars 25, with their flanges extendingvoutwardly, the bars beingsubstantially the same length As spacing means for the ends of thebolster I provide dish-shaped members 26, with their flanges extendingoutwardly, the same being riveted to the sides and bottom'of thebolster, the rivets passing also through the angle-bars 25 and theflanges 16. To these upper outwardly extended angle-bars I rivet a toptension-plate'27, as is shown in Figs. 1 2, and 3. The angle-bars.

28, secured to the sides of the truck-bolster,

extend over only a part of the length of the bolster, as is shown'v inFig. 1, and to these angle-bars I rivet a compression-plate 29. At theends of the bolster the dish-shaped members 30 act as spacing means tohold the sides apart and at the saine time join them together, thesemembers being riveted to the sides and bottom of thefbolster, as shownin Figs. 2 and A3. It will be clear that these upper angle-bars-may befastened to the sides, so that their outwardly-extended flanges would besome distance above the upper edges of the sides. By 'so doing I mayvary the depth of the sides 'of the bolster and IOO strength of the sameand am 'enabledto use a standard size bolster for cars which requiresuch structures of different strengths or depths. The strength of thebolster may also be varied by using angle-bars of differ` v' tendingupwardly and riveted to the sides portion of its len ing saidoutwardly-extended flanges,

adjacent to their upper edges. It will be seen from this constructionthat I secure an especially 'strong/structure, since the integral flanes of this channel-bar 31 are riveted di` rect y to the sides. y

While I have herein shown and described the preferred embodiments of myimprevements, it isl to be understood, however, that the details may bemodified without departfrom the invention, and accordingly I d'o notlimit myself to these details, except to the extent that they are madethe subjectmatter of specific claims..
